CARTRIDGE-SHELL-TRlNllVllNG MACHINE.

SPECIFICATION formingpart of Letters Patent No. 681,2519, dated August 27, 1901. Application filed October Z8, 1895. Serial No. 567,156, (No modeLl To blt whom zt may concern:

13e it known that I, PAUL BUTLER, of Lowell, -countyof Middlesex, State of Massachusetts, have inventedan Improvement in Cartridge- Shel1- Finishing Machines,of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The present invention relates to a machine for finishing the outer ends of cartridgeshells, either metallic or paper, the said ends usually being rough or uneven after the shells are otherwise complete. In the case of metallic shells the machine operates to trim the end and bevel the inner edge of the mouth of the shell, so that the open end of the Vshell will be perfectly smooth and circular and its inner surface slightly flaring for vthe ready entrance of the bullet. A similar operation is necessary in .the case of paper shells, except that in this case a different tool is used, which is adapted to iron or smooth the outer edge of the shell and give it a -true circular outline.

'lhe machine embodyingft-he presentinvention is adapted to receive shells fed thereto upon a movable carrier having an intermittent feed, whereby the said shells are consecut'ively carried to"a predetermined position in which they are held stationary, while the finishing-tool is brought into a position to cooperate with the said shells to perform the desired finishing operation.

The present invention consists mainly in a novel combination of instrumentalities whereby these ends may -be accomplished, and is embodied in a machine comprising a carrier adapted to receive the shells, a rotating cutter or ironing-tool .to operate upon ashell or a gang of such tools operating simultaneously upon two or more shells, a holder for each shell, adapted to confine it in-the proper position tobe operated upon by the aforesaid tool, and an operating-shaft adapted by its rot-ation to cause the said parts to opcrate in such relation to each other as to perform their functions in a proper'manner.

Figure 1 is a top plan View of a machine embodying the presentv invention; Fig. 2, a longitudinal vertical ysection through the axis of the main shaft thereof; Fig. 3, an end elevation looking toward the left of Fig. l, with parts of the cam-wheel broken away to show the carrier and feeding mechanism behind it,`

a portion of the carrieralso being shown in section; Fig. 4, a vertical cross-section on line x4, Fig. 2; Figs. 5 and (i, details of the shell-holder, being respectively a side and end elevation thereof; Fig. 7, a detail ofthe track or support for carriage b; Figs. S, 9, and l0, details of the cutters for metallic shells, and Fig. 1l a modification 'showing an ironing-tool for finishing paper shells.`

The machine embodying the present invention consists of one or more tool-shafts a, mounted to rotate in a reciprocating carrier l), longitudinally movable in a track c at the base of the machine. The said carrier is actuated by a cam d upon the main shaftB and during the movement produced by a revolution of said main shaft carries the tools c2, connected to the shafts a, to and from the shells to be operated upon, which are fed to a carrierj, provided with intermediate feed mechanism cooperating with the reciprocating carriage, so that the shells are brought to a position to be operated upon bythe tools e2 at the forward movement of the carriage b and at the next feed movement of the carrier, which takes place as the carriage b recedes, are carried forward beyond the path of the tools toward a suitable clearer or ejector by which the finished shells are removed from the machine. The same feed movement of the carrier brings other unfinished shells into the position to be operated upon at the next forward movement of the carriage b. The

said tool-shafts a, which may be of any de-I sired number, (the machine as herein shown having three of such shafts,) are mounted in bearings b2 upon the said carriage D, and, as herein shown, said carriage is sleeved upon the main shaft B of the machine,kwhich extends longitudinally from one end tothe other thereof and is driven by a belt upon the pulley 132. To produce the reciprocating movement above described, the said carriage is provided with an arm b3, extending outward therefrom longitudinally with relation to the machine and provided with a cam projection b4, extending into the cam-groove d, formed in a hub (Z2 upon the main shaft B and secured IOC thereto, so'as to rotate therewith, preferably Y by means of screws (73, extending through the webbing of the pulley l2 into the end of the said huh (Z2. Thus as the shaft rotates the cani-groove will engage the cam projection b", causing the entire carriage to travel back and iorth, carryingwith it the tool-shafts a., which are mounted to rotaie therein. As heroin shown, the cam projection Irl islongitudinally adjustable with relation to the earringe, so that the position thereof at its forward movement may he `varied when it is desired to operate upon shells or diil'erent lengths. To thie` en d the said cam projection is secured to the arm Ui hylneans of a holt ZP, bearingin upward projections b and prevented 'from longiliidinal movement with relation thereto hy a huh bl, so that the said bolt is turned the cani projection h1 will be longitudinally moved with relation to the said arm, thus determining the limit of movement of the carriage Z1. The said cam projection when thus` adjusted may be locken in position hy means of a nut hs, as shown.

The tool-shafts a. above described are adapted to receive at their outer ends suitable tools e2 to operate upon the ends of the cartridges, and the said tools are detachably secured thereto by means of a tongue eg, inserted in a socket ft2 at the end of shaft ct and secured therein by a set-screw di. The shafts thus carrying the tools are provided with pulleys o4, adapted to he constantly rotated hya belt of?, p; "ting alternately around said pi'llleys, as best shown in lfig. t.

In order that the cutters-hatte d may be prevented from longitudinal movement with relation to their hearings Ui d uring the operation of the machine and at the saine time he to some extent adjustable longitudinally, the said hearings Ware in extensions at the upper part ol the carriage l), hei-weon which extensions the pulleys f are adapted to fit closely. The said pulleys o4 in turn are mounted upon i he shafts d and secured thereto by setscrews d, so that by looseninpr the set-screws` the shafts (t may he moved with relation to the said pulleys. Thus hy loosening; the said set- .screws and moving the shafts longitudinally with relation to the pnlleysand hearingsthe position arrived at hy the lool during' the forward movement or thc carriage mayhe modilied.

ln order that such adjustment may he deliA eately cliceized, au extension h" is provided at the lli-lol; ol' the carriage, the said exten;

' sion heine' of sui'icientwidth to cover the rear ends of` all the tool-shafts, and through the saideitension are screwed bolts b1", one i'or each.lolljeaid slmfts, adapted to engage thcn'tnrithJ so that hy turning' thc said holte [he :iaid ,shal`t may he moved forward with relation lo the hearings lf2 and pulleys ai. Thus ill it` lound that the cutting-tools are not moved `forward hy the carriage toa suf iieientlyfadranceil position to jyfiroperly trim the shells the seifscrews d upon tho pulleys maybe loosen ed and the hol ts hm Screwed in so that the ends thereoi engage the ends of the eeneee shafts o, forcing the said shafts forward to the desired position, after which they maybe secured by tightening the set-screws @"gwhilo the bolts hhare locked in position by the locknuts bl. Thus at each complete revolution of the main shaft of the machine the constantly-rotating cutter or trimming-tools are advanced by the carriage l), operated hy the cani-groove (il, to a certain position and afterward withdrawn therefrom, au d in order that said tools may be caused to operate as desired upon the cartridge-shells it becomes necessary to provide mechanism for bringing the said shells consecutively to a position in which they will he operated upon hy said tools during,r the forward movement thereof and holding` them stationary in -such position until the operation is performed. "For this purpose a carrier for the shells is provided eon- Sistiner of the wheel or dislrf, having' a hearing, shown, upon the main shaft l5, but not connected to rotate therewith, and having upon its periphery a series of transver. e recesses f2, each adapted to hold a cartridge shell, the said shells preferably being fed thereto through a. chute g, leading downward from the receptacle g2, adapted to contain the unfinished shells. 'lfhe shells are so fed to the said chute that as they pass downvthe carrier they will fall into the transverse recesses ol said carrier with their open ends projecting'inward toward the center oli' the machine, the finishing-tools boing arranged on an are corresponding to the circumference oi the carrier and lin'ojecting toward the periphery thereof and so spaced that each one is directly opposite one of the recesses f2 upon said carrier, and thus adapted when it approaches the same d uriug the forward movement of the carriage to coperate with the mouth of the shell held therein and perform the necessary operation thereon. Thus, assumingthat the carrier f is sta tionary, with shells in the recesses f2 opposite the cutting-tools @2, a rotation oi' the main shaft ll will through the action of the calngroove d canse the carriage b lo approach the said oarrierf, so that the rotating cuttingtools e2 enter the open ends of the shells upon the carrier, trim ming and finishing the saine, as is desired, the carriage afterward being withdrawn by the latter half of a single revolution of the shaft.

ln order that the tooleat the next revolution of lthe shaft may again perform their functions upon a new set of unfinished shells, it is necessary to provide feed mechanism for the carrier and arrange said feed mechanism to operate during the movement ot' the tools trom and to their operative position. '.This is preferably accoinl'llished, as shown herein, by means of a ratchet f3, Fig: S, connected with the carrier and adapted to cooperate with the pawl h, pivoted at h2 upon an arm t', made fast to a rooleshaft ti, extending lonf gitudinally through. the machine, froinfthe.

opposite'end of which rocleshaft projects an IOC IIO

l'upon the cam j, rocking the shaft t2 and actuating the pawl 7i, the cam being so positioned with relation to the cam -groove d that it reaches the projection t4 when the said camgroove d is operating to withdraw the oarriage b'from the carrier f so that when the Y jsaid carriage is thus withdrawn the rock-shaft 2 actuates the pawl h, moving the' carrier f forward, the teeth of the ratchet f2' being so spaced that the completed shells are carried beyond the line of the finishing-tools, while other incomplete shells in the carrier are brought into a position to be operated upon at the next forward movement of the said tools. In order to restore the pawl h at the end of each feed movement, so that it will eugage another tooth of the ratchet-wheel ready for the next feed movement, the arm i3 is arranged so that its weight tends to rock the rock-shaft i2 toward the right, Fig.- 4; butin order to make the operation thereof more positive a guard 7'2 is provided wit-hin the pul- 4ley B2, adapted to coperate with the cam j and engage the projection i4 from the arm t2 when it reaches the end of the cam j, so as to insure the movement of the rock-shaft in the right direction. The pawl h is held in engagement with the ratchet-wheel f2 by means of a spring h3, connected to the arm l, as by screws h2, and bearing upon the upper surface of the said pawl.

In order that the feed movement of the carrier may be slow and gradual, thus obviating the danger of overthrowing or passing beyond. the point at which the carrier should stop, as might be likely to occur owing to the momentum of the carrier if the feed movement were sudden or rapid, the camjlis made, as

shown, with a gradual upward slope extend-v ing some distance around the periphery of the pulley B2, so that the movement of the rock-shaft which actuates'the pawl is gradual, causing the carrier to move slowly, so that it acquires very little momentum. As an additional safeguard, however, it is best to provide a retarding device, and such a device is herein shown, consisting of a split collar f, fitted closely around a hub or projection f5 from' the carrier f, the said collar being supported upon an upright f, secured to the bed-plate of the machine. l

In providing for the proper feeding of the shells it is obvious that the carrier must be arranged to move forward a numberof spaces equal to the number of tools employed in order to prevent the sameshell from being operated upon twice, while the tools must be so spaced that a shell iinished by a tool will be carried to a point which is not opposite the next one. As shown herein, the bearings of the tool-shafts occupy so much space that it is impracticable to place the tools as near'to-- they are accordingly arranged four spaces apart, so lthat the second feed movement carries the shell previously finished by the first cutter two spaces beyond the second cutter, while the third feed movement carries it one space beyond the third cutter, the two unfinished shells immediately behind it being iinished by the third and second cutter, respectively, at. successive operations. In other words, the rst cutter operates on every third shell beginning with the first, the second on every third shell beginning with the third, and third on every third shell beginning with the second. The result is attainable'by placing two cutters any number of spaces apart not equal to their own number or a multiple thereof.

It is obviously necessary for the carrier to 'stand at exactly the right position when the tools are acting on the shells, since otherwise the tools might not register properly with the shells, in which case the shells would be spoiled, while the machine itself might be damaged. In order to`secnre the'proper positioning of the carrier at the end of each feed movement, a centering and locking projection b12 is secured, as by bolts or capgether as are the recesses on the carrier, and

screws 1912, to the front of the carriage b, the

said projection being adapted to n iove with the carriage toward the periphery of/the oarl rierf, the end thereof passing into oe of the recesses f2, and thus locking the/carrier in proper position. I Asclearly shown in Fig. 2, the main portion of 'said proj eotion 1512 is substantially the same in shape asv the recesses f2 and will thusYV fit closely therein, preventing any movement ofthe carrier f, whilethe end loli/the said projection?)12 is made some- IOO what/taperingcfthat it will/enter the recess evenif the caier is slightly out of its proper position, and by i/ts'ffnr'ther movement will act as a wedgctobring the carrier to the right' position fand lock it there during the operation of the tools.

In order that the shells may be firmly held in the carrier during the time when the tools are operating thereon and at the same time be temporary holders le are provided, one corresponding to each of the tools and arranged to coperate with the shell in the recess opposite said tool. In order that the said holders may not interfere with the feeding of the shells, they are arranged to operate intermittingly to correspond with the intermittent feed movement of the carrier--that is to say, they are arranged to engage the shells after the carrier has stopped with the shells in position to-be. operated upon bythe tools and to be disengaged therefrom at the end of vsuch operation in order to permit the onward feed movement of the carrier. To attain this end, the said holders consist of arms pivoted in lugs k2 upon the top of au upright A, in which Iio is formed one of the bearings for the shaft B, i

and the said arms extend outward overthe 115 i readily fed thereto and detached therefrom,

carrier, each being provided with a clamp portion 7:.3, adapted when the said arm is rocked on its pivot to close down upon the upper side of the shell, thus holding it rmly in its recess upon the carrier. The said clamps are preferably pivotally supported at 7.1, (see Fig. 5,) so that as they are pressed down `upon the upper surface of the shell they Will move upon their pivots into substantial parallelism therewith, and they are each provided with a spring 71'?, adapted to hold them substantiallyin the position shown in Fig. 5, and are, as shown, mounted in a slot l.:U at the end of the arm 7s, whereby they are longitudinally adjustable with relation to the said arm to a greater or less extent, as may be desired. The said arms 7s are normallyheld in the position shown in Fig. 2 by means of springs k7, the said position being such that the shells are not engaged by the clamps, but are free to move under `the said clamps during the feed movement of the carrier. In order to cause the said clamps to operate lat the end of each feed movement, and thus hold stationary the shells at that moment in position to be operated upon, each of the said arms is provided with a cam-roll .li-S beyond the pivotal support 7g2, and the said cam-rolls when the arms l; are in their normal position rest upon the surface m2 of a cam-wheel in, mounted upon the main shaft B, so as to rotate therewith. The said eamwheel is provided with cam-surfaces m3, consecutively arranged, -as shown, each of said cam-surfaces extending over only a portion of the periphery of the cam-wheel 'In and being arranged one in advance of the other, while the cam-rolls It are so positioned with relation to the surface of the cam-whecl in that each one is adapted to cooperate with one of said cams and not with the others. Thus, referring to Fig. l, it will be seen that as the shaft ll rotates in the direction of the arrow shown upon the cam-wheel `In thefore most of the said cam-surfaces on will pass the first two of the cam-rolls 7n@ without engaging therewith, while the second of said surfaces m3 will pass the first of said cam-rolls, the third cam-surlaee, however, being posi tioned to reach the first of the cam-rolls at the time when the other two cam-surfaces rcspec tively meet the other two cam-rolls, thus practically lifting all of the said eain-rolls simultaneously and rocking all of the clamping-arms 7.', upon their pivots, so as to clamp three shells in their respectivo carrier-re cesses at the same time. The canrsurlaces fm. are of such length as to maintain the holders lin their clamping position during the operation of the cutters upon the cartridgeshells held thereby, but terminating consecutively when the shaft B has reached that portion of its revolution at which the carriage Z7 has been withdrawn, by' the cam-groove d to disengage the tools from the shells previously held. The cani-rolls iti then descend from the camssurfaces m, and the holders 7c are restored to theirnormal position (shown in Fig. 2) by means of the springsr, above 1nentioned. .Thus dnringasingle rotation of the main shaft B the carrier f is fed forward a predetermined distance, the holders 7c are brought into engagement with the shell to be operated upon, the tools are advanced to ward the'said shells by the movement of the carrier,so as to perform their operations on the said shells, and are again withdrawn from the carrier, the holders released, and the carrier again fed forward, carryingr the finished shells beyond the point at which the cutting-tools operate and bringing a new set of unfinished shells to the operating position, after which the operation is repeated. The limit of move'- ment of the holders 7a can be adjusted for shells of different sizes by changing the position of the cam-roll, the bearing lo for which is vertically adjustable in the slot 7cm by means of the screw 7c and nut 701i.

The clamps above described, while being operated with sufficient pressure to prevent the shell from being lifted out of the groove, are not necessarily capable of holding the shell firmly in its propervlongitudinal position against the thrust of the cutting-tool en gaging therewith. For this reason an abutment A2, projecting from the upper part of the upright A, is provid ed, the said abutment following the periphery of the carrier, so as to be opposite to the tools, the face of the abutment being close to the rear of the oarrier, so that as the carrier rotates the rear ends of the shells will bear against the said abutment,theshells thus beingheldlongitudinally while the cutters are operating thereon.

ln order to remove the linished shells from the carrieres the said carrier is fed onward, a clearer f7 is provided, consisting of a thin strip or plate of metal extendinginto a slot j8 upon the periphery of the carrier f, `the said plate havingacurved edge ff beginning within the said slot and curving outward therefrom beyond the periphery of the carrier, so that as the shells approach the said plate they are engaged by the edge f" and carried outward from the carrier thereby, as will he clearly seen by reference to Fig. 3, where a` portion of the carrier-wheel is shown in section with the plate/L'T in elevation.

In order to clear the `recesses f2 of any dust or metal chips which may have collected therein and which might,if. allowed to remain, alter the position of the shell with relation to the tools and thus cause damage, a brush or clearer may be employed, such a device being shown herein as consisting of an ordinary brush 91, (see Fig. 3,) mounted on an arm n.2, supported in an undercut slide or guideway n3, just below the chute g, through which the shells are fed to the carrier. The said arm 'a2 is adapted to travel in said guideway, and thus carry `the brush n. across the periphery of the carrier and longitudinally through the reoessesf2 therein, and, as shown herein, the said arm n.2 is connected by a linlr n", Fig. l,

IOO

to an arm n.5, pivoted at n to a portion of the frame of the machine. The said arm ns is adapted to be engaged by a projection nl, extending outward from the carriage b, the said projection being shown in dotted lines, Fig. 3, so that a's the carriage moves forward it rocks the arm 'if upon its pivot fn, moving the brush across the periphery of the carrier, and the said brush is then moved back toits normal position by means of a spring n.8 when the carriage l) moves back, so that the projection 'nl no longer pushes the. arm n.5. As has been above mentioned, the carriage b, as clearly shown in Fig. 2, is sleeved or mounted upon the main shaft B of the machine, so asv to be longitudinally movable with relation thereto, but is mainly supported in the track or guideway w, mounted upon the bed of the machine, and the said track or gnideway is preferably contained in a supplemental supporting portion c2, having transverse slots c3, (shown in detail Fig. 7,) said slots having an inclined surface adapted to be engaged by a Wedge-shaped key cl. The track or guideway c is supported on the upper surface of the key or keys c, two beingshown herein, so that the carriage Z1 is capable of a slight vertical adjustment, or, in other words, may be trued up until it is exactlycentered upon the main shaft l5, so that the said shaft is relieved of the weight of thc carriage and frictional re sistance to the longitudinal movement of the carriage, as well as to the rotation of the shaft, which would be caused by the said weight upon the shaft. As herein shown and as thus far described, the machine is adapted to trim and finish metallic shells, and the cutters may be of any construction suitable for that purpose, one of said cutters, however, being shown in detail in Figs. 8, 9, and l0 and having a guide projection or tongue e4 at its outer end adapted to enter the mouth of the shell, the said tongue being tapering and provided with a cutting-blade c5, contained in a slot e and secured by a screw c7, thus being longitudinally adj ust-able, said cutter being adapted to bevel the inner edge of the end cf the shell, While a second knife or blade es extends radially from the said tongue, so as to trim the extreme end of the shell during the rotation ofthe tool. The blade e3, as herein shown, consists of a single piece having cutting edges on opposite sides and a squared portion between adapted tc be held in a transverse opening e9 through the projection e4 by a set-screw cw entering the end of said projection. The machine, however, is equally well adapted for finishing paper shells, it being necessary only to substitute an ironingtool for the cuttingtools above described and to slightly modify the carrier to fit the paper shells. A practi- -cal tool for this purpose is shown in section in Fig. 1l., said tool consisting mainly of a tapering tongue or mandrel e2", adapted to enter and engage the inner surface of the shell and provided With a collar ci, secured thereto in any suitable Way, as by a set-screw c, the

with grooves c, extending from its point or 4 outer end back to a point beyond 'the collar e3", thus forming channels through which bits of material removed from the inner surface of the shell by the said mandrel are free to work back and drop out. 'lhe nature of the tools, however, is obviously not essential to the invention, since a tool of any kind can be employed, the substitution of one for another requiring but slight modification, if any, in the general construction of the machine.
